Hi,
I have just released new versions of all Closer libraries, including Closer to MOP and ContextL.
A major change that affects all libraries is that I have dropped support for Macintosh Common Lisp, and "replaced" OpenMCL with Clozure Common Lisp. Furthermore, the dependency of Closer to MOP to LW-Compat has been removed due to requests by users, but a dependency of ContextL to the portable-threads librarie of the GBBopen project has been added.
Other highlights include:
## Closer to MOP 0.5 ##
+ In MCL, OpenMCL and Clozure Common Lisp, funcallable-standard-object is now exported from Closer to MOP.
+ Fixed the lack of :generic-function-argument-precedence-order- returns-required-arguments in Allegro Common Lisp.
+ Ensured that a defgeneric form makes a generic function metaobject available in the compile-time environment. Otherwise, defmethod may not yield a method of the correct method metaobject class.
+ Added support for compute-discriminating-function in Clozure Common Lisp and OpenMCL, based on code provided by Slava Akhmechet.
+ Added a classp predicate (due to Willem Broekema).
## ContextL 0.5 ##
+ Added :in as an alternative for :in-layer in the various define- layered-xyz macros.
+ ContextL now depends on portable-threads of the GBBopen project. This is done for locking critical sections to ensure thread safety of ContextL.
+ Added new functions active-layers and (setf current-layer-context).
+ Added a garbage collector for layer caches, such that redefinition of layers or certain methods in the ContextL MOP have an effect.
+ Simplified mapping of layer-related names to internal names, which should also make things easier to read when debugging ContextL programs.
## MOP Feature Tests 0.45 ##
+ Added new recognized standard feature :generic-function-argument- precedence-order-returns-required-arguments.
+ Added a new known extra feature for SBCL (since SBCL version 1.0.14).
The libraries can be downloaded from http://common-lisp.net/project/closer/ and are asdf-installable, as usual.
Best, Pascal
